How To call a function in php oop class? using ajax?

[Exequiel]

Hello friends, i want to know if how to call a php oop class function like mainCategory using ajax, this is the code for ajax,

var d = "Zick";
$.ajax({
		type: "post",
		url: "e_class.php/mainCategory",
		data:{
			d:d
		},
		success: function(inlog){
			alert(inlog);
		}
	});

and this is for the php

class E_class
{

	public function mainCategory()
	{
		echo $_POST['d'];
	}	

}

I made it with codeIgniter but without codeigniter i can't call the funtion, , any reply are appreciated. . :D

you cannot call a class directly from AJAX, only a whole script. (but you can of course use an URL that indicates you want a certain class to be called).
